> Project: Derby
> Issue Type: Bug

> Create a database called "wombat" with Derby 10.10.2.0.
> Then, in the same directory, execute the following code using the 10.11.1.0
> release candidate:
> {code}
> Connection c = DriverManager.getConnection("jdbc:derby:wombat");
> c.setAutoCommit(false);
> Statement s = c.createStatement();
> s.execute("create table t(i int generated always as identity)");
> s.execute("insert into t values (default)");
> c.rollback();
> {code}
> The INSERT statement will fail with a self-deadlock:
> {noformat}
> Exception in thread "main" java.sql.SQLTransactionRollbackException:
> Self-deadlock.
